EMI Shielding Gasket Reinforced Graphite Sheet With RoHS Compliant

Products Description
 

RoHS-Compliant Flexible Graphite Gasket Solutions

Material Science & Manufacturing

1. Chemical Exfoliation: Graphite flakes undergo intercalation with sulfuric acid to create expandable graphite.
2. Thermal Expansion: Heated to 1000°C+, producing worm-like structures with a bulk density of 0.003g/cc.
3. Cold Rolling: Compressed into binder-free coils/sheets, ensuring 99.9% purity and halogen-free composition.

Key Advantages for RoHS-Required Industries

1. Toxic Substance Free
   • Complies with EU RoHS 2011/65/EU (Restriction of Hazardous Substances).
   • Contains <0.1% lead, <0.01% cadmium, and zero mercury/chromium VI.
2. Multi-Industry Adaptability
   • Electronics: EMI shielding gaskets for smartphones/tablets (IEC 61373 compliance).
   • Automotive: Engine compartment seals resisting glycol-based coolants (SAE J2006).
   • Medical: Non-toxic seals for MRI equipment and pharmaceutical pumps (USP Class VI).
3. Performance Metrics
   • Temperature Range: -200°C to +1650°C (oxidation resistance up to 500°C in air).
   • Compressive Strength: 45-60 MPa (ASTM F36), with 90% recovery after 10,000 cycles.
   • Gas Permeability: <0.01 cm³/(m·s·Pa) for helium leakage (ASTM D1434).
